Question
As shown in the drawing, a positively charged particle remains stationary between particles A and B. The positively charged particle is one-quarter the distance between the two other particles, as shown. What can be concluded from the situation?
Question options:
A)
B is positively charged and A is negatively charged.
B)
A and B have equal negative amounts of charge.
C)
A is positively charged and B is negatively charged.
2. Which one of the following statements best describes the concept of the electric field?
Question options:
A)
The electric field is a distribution of vectors at points due to the presence of one or more charged objects.
B)
The electric field is a scalar quantity related to the total amount of charge on one or more charged objects.
C)
The electric field is a vector quantity that is the reaction force of electrons.
D)
The electric field at each point is the potential energy of a test charge divided by the amount of the test charge.
E)
The electric field is a scalar field, which has a magnitude at each given point, similar to the temperature or pressure field.

Explanation / Answer
1. ans-C:- A is positively charged and B is negatively charged(because positive charge have between A and B so particle A away from and B towards)
2.ans C:-The electric field is a vector quantity that is the reaction force of electrons
3.ans D:-The electric field is directed away from the electron and has a magnitude of ke/r2
